Swoopie neck fix and couple other tweaks

Fixed "speedy" vorgans not getting removed from SSbellies processing list, and also switches those from mob subsystem to obj subsystem to reduce lag.
Optimized some mob processing as well, mainly by making simplemob carboncorpses, monkeys, brainmobs, and observers low priority processing for the mobs subsystem.
Also swapped swoopie's main gut fullscreen to a more appropriate one.
